2inch 3inch 4inch InP epitaxial wafer substrate APD mai gano haske don sadarwar fiber optic ko Hoton Fetur na LiDAR

Takaitaccen Bayani:

InP epitaxial substrate shine tushen kayan masana'anta na APD, yawanci abu ne na semiconductor wanda aka ajiye akan ƙasa ta hanyar fasahar haɓaka epitaxial. Abubuwan da aka saba amfani da su sun haɗa da silicon (Si), gallium arsenide (GaAs), gallium nitride (GaN), da sauransu, tare da kyawawan kaddarorin lantarki. APD photodetector wani nau'i ne na musamman na photodetector wanda ke amfani da tasirin photoelectric avalanche don haɓaka siginar ganowa. Lokacin da photons suka faru akan APD, ana samar da nau'ikan ramukan lantarki. Haɓaka waɗannan masu ɗaukar kaya a ƙarƙashin aikin wutar lantarki na iya haifar da samuwar ƙarin masu ɗaukar kaya, “sakamakon dusar ƙanƙara”, wanda ke haɓaka fitarwa na yanzu.
Epitaxial wafers wanda MOCvD ke tsiro shine babban abin da ake mayar da hankali ga aikace-aikacen diode photodetection na dusar ƙanƙara. Abun U-InGaAs ya shirya abin sha tare da bayanan doping <5E14. Layer na aiki zai iya amfani da InP ko InAlAslayer. InP epitaxial substrate shine ainihin kayan don masana'antar APD, wanda ke ƙayyade aikin ganowar gani. APD photodetector wani nau'i ne na babban mai gano hoto, wanda aka yi amfani da shi sosai a fagen sadarwa, ji da kuma hotuna.

Mabuɗin fasali na takardar InP Laser epitaxial sun haɗa da

1. Band rata halaye: InP yana da kunkuntar band rata, wanda ya dace da dogon-kalaman infrared haske ganewa, musamman a cikin zangon kewayon 1.3μm zuwa 1.5μm.
2. Ayyukan gani: Fim ɗin Epitaxial na InP yana da kyakkyawan aikin gani, kamar ƙarfin haske da ƙimar ƙima na waje a madaidaicin raƙuman ruwa daban-daban. Misali, a 480 nm, ƙarfin haske da ƙimar ƙimar waje shine 11.2% da 98.8%, bi da bi.
3. Ƙwararrun Ƙwararru: InP nanoparticles (NPs) suna nuna halin lalata sau biyu a lokacin girma epitaxial. Lokacin lalatawar sauri yana da alaƙa ga allurar jigilar kaya a cikin Layer InGaAs, yayin da jinkirin lalata lokaci yana da alaƙa da haɗuwar mai ɗauka a cikin InP NPs.
4. Babban halayen zafin jiki: AlGaInAs / InP quantum rijiyar abu yana da kyakkyawan aiki a babban zafin jiki, wanda zai iya hana yaduwar rafi da inganta yanayin zafin jiki na Laser.
5. Tsarin masana'antu: InP epitaxial zanen gado yawanci girma a kan substrate ta kwayoyin katako epitaxy (MBE) ko karfe-organic chemical vapor deposition (MOCVD) fasahar don cimma high quality-fina-finai.
Waɗannan halayen suna sa InP Laser epitaxial wafers suna da mahimman aikace-aikace a cikin sadarwar fiber na gani, rarraba maɓalli na ƙididdigewa da ganowar gani mai nisa.

Babban aikace-aikace na InP Laser allunan epitaxial sun haɗa da

1. Photonics: InP lasers da detectors ana amfani dasu sosai a cikin hanyoyin sadarwa na gani, cibiyoyin bayanai, infrared imaging, biometrics, 3D sensing da LiDAR.

2. Sadarwa: Abubuwan InP suna da aikace-aikace masu mahimmanci a cikin babban haɗin kai na laser na dogon lokaci na silicon, musamman a cikin sadarwar fiber na gani.

3. Infrared Laser: Aikace-aikace na InP-based quantum well lasers a cikin tsakiyar infrared band (kamar 4-38 microns), ciki har da gano gas, gano fashewa da kuma hoton infrared.

4. Silicon photonics: Ta hanyar fasahar haɗin kai iri-iri, ana canja wurin Laser ɗin InP zuwa madaidaicin tushen silicon don samar da dandamalin haɗin gwiwar silicon optoelectronic multifunctional.

5.High aikin lasers: Ana amfani da kayan InP don kera manyan lasers, irin su InGaAsP-InP transistor lasers tare da tsayin daka na 1.5 microns.

XKH yana ba da wafers na InP epitaxial na musamman tare da sassa daban-daban da kauri, yana rufe aikace-aikace iri-iri kamar hanyoyin sadarwa na gani, na'urori masu auna firikwensin, tashoshin tushe na 4G / 5G, da sauransu. Ana ƙera samfuran XKH ta amfani da kayan aikin MOCVD masu ci gaba don tabbatar da babban aiki da aminci. Dangane da kayan aiki, XKH yana da nau'ikan tashoshi masu yawa na kasa da kasa, yana iya sarrafa adadin umarni cikin sassauƙa, da samar da ayyuka masu ƙima kamar su bakin ciki, rarrabuwa, da sauransu. inganci da lokutan bayarwa.
